I’ve been using this card for a while but it seems 2023.5 breaks it. I tried the beta but rolled back when I saw the issue. Anyone having issues with this after the latest May update?
During the pre-2023.5 releases we got warned about the Polymer component that is listed for deprecation.

In the dashboard it shows:
I think we have to come up with another custom JS file to make the buttons work for the fans.

Here is a HACS repo with a 6 speed button row for Modern Forms fans. I simplified the code quite a bit so it could be easily modified if need be. Let me know if this helps.
